Earlier analysis has proven that social affect can drive rooftop photo voltaic adoption. Analysis so far has primarily targeted on affect between households, however sure types of social affect can also exist between non-residential and residential installations. For instance, a person might resolve to undertake after seeing photo voltaic panels put in at an area enterprise or after studying {that a} native establishment is powered by photo voltaic. The potential affect of non-residential photo voltaic techniques on residential adoption selections has been under-explored.

In a brand new paper, researchers from Berkeley Lab, the Nationwide Renewable Vitality Lab, and Tufts College discover whether or not and to what extent non-residential photo voltaic installations affect residential adoption developments in surrounding neighborhoods. The researchers attain three predominant conclusions.

First, the info counsel that non-residential photo voltaic installations on companies, authorities buildings, faculties, and homes of worship enhance residential photo voltaic adoption. Throughout varied fashions, the outcomes counsel that residential adoptions enhance by round 1 to 4 adoptions per quarter in areas the place a non-residential system has been put in.

Second, the estimated magnitude of affect from non-residential buildings is similar to the estimated magnitude of affect from residential buildings. That’s, the analysis means that people are about as prone to be influenced to undertake photo voltaic by a close-by non-residential set up as by a close-by residential set up.

Third, the outcomes counsel that the diploma of affect varies throughout totally different constructing sorts, although additional analysis is required to estimate variations extra exactly and the supply of these variations. The researchers posit that the relationships between various kinds of establishments and their communities might clarify variations in affect. As an illustration, faculties and homes of worship straight have interaction with native communities in methods which have been demonstrated to affect conduct in different areas and will likewise affect photo voltaic adoption selections.

Like different photo voltaic affect analysis, the Berkeley Lab examine solely estimates the quantitative affect of affect however doesn’t establish how or why that affect happens. Future analysis might discover particular mechanisms for non-residential affect on residential photo voltaic adoption selections, similar to visible cues, direct interactions between non-residential establishments and communities, installer-related mechanisms, or different components.

The Berkeley Lab examine, Impacts of non-residential photo voltaic on residential adoption selections, is revealed within the Journal Frontiers in Sustainable Vitality Coverage, and is offered right here. The authors will host a webinar on February 7, 2023, at 11:00 PT/2:00 ET. Register right here: https://lbnl.zoom.us/webinar/register/WN_vvJ_GreUQAq2p1v-YJ455g.
